RamDisk Plus 12 for Desktop Systems

SSDs are faster than HDDs. If you have a real need for maximum speed then
a RamDisk is the correct choice. It is faster than either of them.

RamDisk vs. Hard Disk Drives (HDD)
The most important difference between a RAM disk and a hard disk is access
speed. The time taken for a regular hard disk to move its magnetic heads
over the spinning disks (much like the arm moving over old vinyl record
disk) is the seek time and is typically measured in milliseconds (thousandths
of a second). Whereas a RAM disk does not have mechanical parts and its
access speed is typically measured in nanoseconds (billionths of a second).
Access to a RAM disk may be 50 times faster or more than to a hard drive.

RamDisk vs. Solid State Drives (SSD)
The SSD “solid-state” technology uses flash memory so it does
not spin like a traditional disk, so there is no disk head “seek”
time. So in a sense an SSD functions similar to a RamDisk.
However, main system RAM is tightly coupled to the CPU insuring the highest
data throughput possible. Whereas SSD typically have to go through some
other slower bus to bring data to the CPU. Additionally there is the issue
of write amplification, which decreases the SSD lifespan and hurts random
write performance and lastly SSDs are still pretty expensive.

RamDisk Plus®

It
uses our patented memory management (up to512
GB) to create a virtual disk out of RAM. The RAM disk
appears like a physical hard disk to the operating system and programs.
You choose its size (depending on the amount of RAM in your system),
drive letter, and file system. You can copy, move and delete files
on it. Like a physical disk, a RAM disk can also be shared so as to
be accessed by other computers on a network. But a RAM disk is volatile
by its very nature. Meaning any data on it will be lost if the system's
power is off.
But this can be mitigated with the backup feature you can read about
below.

RamDisk Plus adds multiple disk support, system page file
support for HDD, and a versatile disk image backup and restore facility. You
can manually save the RAM disk’s contents to an image file, or have
the contents saved automatically when the computer is shutdown. This feature
ensures that service and application data stored on the RAM disk can be preserved
between system restarts. During the subsequent system start-up, the disk's
image is automatically loaded. A "live" RAM disk image may be backed
up even with open handles to the volume. A RAM disk image viewer is included
and lets you load image files as read-only devices. RAM disks can be zeroed
out upon removal and the disk image file can be preserved upon removal.

Extended memory access

RamDisk Plus
12 has a most unique feature. Our patent pending technology
can access memory beyond the limitation imposed by a Windows 32-bit
operating system! In other words, RamDisk Plus 12 can use "unmanaged"
Windows' memory e.g. above 4GB. It can also use the stubbornly inaccessible
memory between 3.2GB and 4GB.

See the product's help file for detailed explanation of what "unmanaged"
memory is and how to access and use it with RamDisk Plus 12.

This feature has now been included into the 64-bit RamDisk Plus version
11.7.917. Any memory not accessible by a Windows 64-bit
OS can now be included for use by a RamDisk! For example, Windows 7 Home
Premium 64-bit can access up to a maximum 16GB of RAM. If your system has
more, then RamDisk Plus can make the extra "unmanaged" RAM above
16GB available for a RamDisk.

Another reason for using a RAM disk is security or privacy. Once the
server is restarted or shutdown, the contents of the RAM disk are lost
(when the auto-save feature is disabled). For some services or applications,
this is an important attribute that contributes to the protection of sensitive
data or information.

"Designed for Windows Vista & XP "

RamDisk and RamDisk Plus have been
thoroughly tested to meet Microsoft standards for Windows 7, Vista and XP compatibility.
Microsoft awards these logos to products that deliver a reliable, high-quality
computing experience with Windows operating systems.

For disk I/O performance benefits similar to RamDisk but with low or
no added risk of data loss, see SuperCache.

* These are the operating system's managed memory
limits. When greater amounts of RAM are in the system then these can be
accessed when our unmanaged memory
functionality is enabled in RamDisk Plus.

Other considerations:

•

16 MB free disk space for installation

•

To support backup functionality, RamDisk Plus
requires sufficient free disk space to store the image file of
each RAM disk. The actual size needed will vary from less than
a megabyte up to the size of the RAM Disk.
